So I just finished it last night and I thought it was pretty good. There's a number of Stephen King references but I didn't feel that they were overbearing.

I did feel though, that despite the length, that it could have been more 'epic'. I found the whole concept of Christmasland to be interesting but we only really see it at the very end.

I also wasn't sure what to make of the "bonus" chapter hidden at the end. Is he setting up for a sequel?

Overall though Joe Hill's still a fantastic writer. If you like his other stuff be sure to check it out.
